The nontrivial topological invariant characterizing the bulk electronic band structure gives rise to the robust edge or surface modes, manifesting the hallmark of a topological material - the bulk-boundary correspondence [1]}, [2]}. As such, these boundary modes have been so far almost exclusively used to experimentally detect nontrivial electronic topology, both in gapped [3]}, [4]}, [5]}, [6]}, [7]}, [8]} and gapless [9]}, [10]} systems. Equally important, but much less explored, is the direct probing of topological states in the bulk without invoking the boundary modes, through their response to topological lattice defects, such as dislocations [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}. Moreover, the topological defect modes
are more pristine and easier to detect being immune to contamination by the interfaces and independent of the surface termination. In fact, in the context of experimental probing of topology in the quantum materials this aspect has started to gain prominence only recently [18]}, [19]}.
